I'd like to create a workflow (ideally in Process Builder) that changes LeadSource on the Lead record after it has been converted when AccountSource is changed on the Account.
Context: inbound leads are automatically created in SFDC when a customer registers on our site. Due to reps not manually entering leads before the customer takes action, reps convert these "Inbound" leads and do not always adjust the lead source before they convert it (i.e. change to "Outbound" as the source). These are easy to catch later on in the sales cycle, but it results in discrepancies between the LeadSource on the Lead object and the later corrected AccountSource on the Account. Our Data Science team uses these converted lead records to look at total lead volume and performance by lead source, and this results in regular QAing and manually changing the lead source on the converted lead record (which is a pain in many ways).
Is there a way to automatically change LeadSource on the converted Lead object when the AccountSource is corrected?
Any insight is much appreciated, thanks in advance!
